Mentor Graphics Corp. disclosed that it has released its next-generation constraint editor system (CES) into its Expedition Series and Board Station RE PCB design flows. The CES tightly integrates with the entire systems design flow from schematic entry through physical layout, facilitating multi-disciplined communication of high-speed design rules and constraints between engineers, designers and their tools.

"Our customers consistently face design cycle time and product quality pressures in today's competitive environment," shared Henry Potts, VP and GM for Mentor's Systems Design Division. "With the superior integration of our CES solution, our customers are able to experience significant productivity gains and improved design quality."

The CES provides a unified interface for design engineers and layout designers to specify and verify constraints. Constraints can be entered in terms familiar to team members through a common GUI and then automatically accessed by individual tools in their native formats. Productivity gains can be realized through usability features such as automatic differential pair identification and constraint templates, which make entering complex constraints much easier, added the company. Advanced automatic topology and an interactive tuning meter are enabled when CES is used in the design flow.

An important aspect of CES is its ability to provide customers with design rules and constraints that can be developed and modified throughout the design process. These rules and constraints then become intellectual property (IP) that is available to designers and engineers for their current and future designs. Mentor said that the ability to reuse the physical design IP through a single entry point for management and access is what sets CES apart from other solutions currently available.

CES also supports bi-directional cross probing, which highlights and selects between a spreadsheet-based constraint interface and the schematic capture and layout tools, enabling designers to view nets and constraints in their native environment. In addition, constraint values are fully synchronized during the forward and backward annotation process with intelligent handling of connectivity changes. Users can create hierarchical rule classes that ease the association of constraints to design objects. Nets can be constrained by one rule at the class level, reducing the number of constraints manually entered in the design. CES also supports user- and pre-defined automatic topologies, enabling quick assignment of pin ordering that is utilized throughout the design process.

Mentor's Constraint Editor System is available immediately at no cost for current Expedition Series and Board Station customers.
